Second Lab Hydrate Lab

Hydrates are ionic compounds that contain an inorganic salt compound loosely bound to water.
The purpose of this lab was to determine the practical formula of a hydrate.


In this lab we determined the mass of the hydrate without water (anhydrous)


We used:
-Bunsen Burner
-Test tube
-Test tube clamp
-Test tube rack
-Weight scale
-Cobaltous Chloride Hexahydrate


First we filled the test tube with Cobaltous Chloride Hexahydrate then weighed it.
Then we began to use the Bunsen burner while using the clamps to hold the test tube over it.
We noticed the Cobaltous Chloride Hexahydrate turn from the color red to a light blue.
Then we re-weighed the test tube.


The percent of water in Cobaltous Chloride Hexahydrate was 45%.
